在 CentOS 7 上將 PHP 5.x 遷移到 PHP 7

在本文中，我們將學習如何將 PHP 5.x 升級和更新到 PHP 7，PHP 7 於 2015 年釋出，其速度改進可與舊版本的 PHP 相媲美。

先決條件

假設我們已經在 CentOS7 上安裝了 PHP 5.x，並且 Apache 應該啟用了 mod_php 模組，我們需要 Sudo 許可權或 root 使用者。

啟用 PHP 7 儲存庫

由於 PHP 7.x 在官方儲存庫中不可用，因此我們需要使用 IUS 社群專案儲存庫。

使用以下命令下載機器上的 IUS 儲存庫

# curl 'https://setup.ius.io/' -o setup-ius.sh
curl 'https://setup.ius.io/' -o setup-ius.sh
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 1913 100 1913 0 0 1554 0 0:00:01 0:00:01 --:--:-- 1555

使用以下命令將 IUS 儲存庫安裝到本地機器

# bash setup-ius.sh
bash setup-ius.sh

升級 Apache 中的 mod_php 模組

在這裡，我們將升級 Apachhe 模組 mod_php 的系統。首先，我們將使用以下命令刪除舊的軟體包。

# yum remove php-cli mod_php php-common

使用以下命令使用 IUS 儲存庫安裝新的 PHP 7 模組。

# yum install php70-mysqlnd mod_php70u php70u-cli

最後，我們將重新啟動 apache 並檢查 apache 的狀態

# systemctl restart httpd

檢查 apache 服務狀態

# systemctl status httpd
httpd.service - The Apache HTTP Server

測試 PHP 版本

我們可以透過使用命令列模式來驗證 PHP 版本，我們還可以建立一個 info.php 並檢查 PHP 的版本

# php -v
PHP 7.0.8 (cli) (built: Jun 23 2016 11:34:57) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies

使用以下程式碼建立 info.php 檔案並在 GUI 模式下檢查資訊。

# /var/www/html/info.php
<?php
Phpinfo();
?>

建立檔案後，使用以下 URL 訪問 Web 瀏覽器

http://IP_Address /info.php

在完成上述步驟的設定和配置後，我們現在可以將 CentOS 7 上的 PHP 5.x 更新到 PHP 7。截至目前，CentOS 7 的官方儲存庫尚未釋出。我們還可以看到 PHP 7 已在伺服器上升級。
